KiXforms

[rjdegraff]

I have an application that I am porting from an HTA to VBS with kixforms (.net). It requires a combobox that responds to a double click. The following code does not get a response to that event? Is this a bug?

Dim System

Set System = CreateObject("KiXforms.System")

Dim Form1

Set Form1 = System.Form
Form1.Text = "Form1"

Dim ComboBox1

Set ComboBox1 = Form1.Controls.Add(System.ComboBox)
ComboBox1.Location = System.Point(88, 57)
ComboBox1.DropDownStyle = 0
ComboBox1.TabIndex = 0
ComboBox1.Size = System.Size(121, 150)

ComboBox1.DoubleClick = "ComboBox1DoubleClick( ComboBox1 )"

Form1.Visible = "True"

Do While Form1.Visible
Execute(Form1.DoEvents)
Loop

Function ComboBox1DoubleClick( Object )
MsgBox "double click"
End Function

I have verified it doesn't work when converted to KiXtart and it also doesn't work in all combobox dropdownstyles.

Will have a look.

According to Microsoft, the ComboBox does not support the DoubleClick event ... here is the link:

http://msdn2.microsoft.com/en-us/library/system.windows.forms.combobox.doubleclick.aspx

Further down it says:

This event is not relevant for this class.

Doesn't surprise me. You may ask "then why is double-click even listed" thats because the ComboBox derives from Control which has the generic double-click event. .Net classes do that much - override a base class method then "nerf" it.

Yeah I thought it was weird for a combobox to support a DoubleClick and I know it derives most of the properties and methods from Control class. I wonder why it was a requirement for rjdegraff.

Can you shed some light, rjdegraff?

Actually, it was a requirement because at the time I didn't realize I was using the wrong control
